But at a Wednesday panel at the Milken Institute Global Conference here, Roubini called the blockchain a “glorified Excel spreadsheet,” noting that cryptocurrency holders still go through centralized exchanges to clear their transactions.

“There is no decentralization, it’s just bulls–t,” Roubini said, using the potty-mouthed epithet no less than four times as he bad-mouthed bitcoin.

“This was a bubble … the ones who arrived late to the party are the suckers, Roubini said, referring to investors who bought Bitcoin last year when it traded at $20,000. It now trades around $9,000.

The crypto-craze — coupled with the flood of bad actors trying to get their piece — has captured the attention of regulators who are grappling with how to treat the space.

“Crypto is not a synonym for immune from the rule of law. We don’t want it to be a safe haven for bad things. We don’t think that mom and pop who invest in it should be ripped off,” Brent McIntosh, General Counsel of the Treasury Department, told The Post in a sidelines interview following the panel.

But McIntosh stopped short of saying what regulation would look like.

“I’ve long since stopped trying to predict what happens on The Hill,” McIntosh said.
